I’ve never really had a reason to go to Greenwich, Conn., before but now I have a reason to go back: “Oscar the Grouch,” the solo show by Urs Fischer at the Brant Foundation Art Study Center. The show presents various pieces of Fisher’s work set in a beautiful stone house on the Greenwich polo field. The awe-inspiring setting (only 45 minutes from New York City!) is nothing compared to the awe-inspiring work that is inside.

Some of the pieces, like the super slick Diet Coke and the halved onion mounted on a giant mirrored box were part of Fisher’s recent New Museum show; and some of you might recall “You” — a huge dug-out hole — which was at Gavin Brown’s Enterprise a few years back, which has been recreated here. But in this case, context is everything.

A new work, “Abstract Slavery” presents life-size copies of two rooms from Peter Brant’s residence. Inside each, a wax effigy of the collector slowly melts away, surrounded by his personal photographs, books and his art collection. It’s almost like being in Brant’s house. If I’m ever invited into the inner sanctum, I’ll know exactly where to go to admire the real Warhols.

The Brant Foundation Art Study Center, at 941 North Street, is open by appointment only Tuesdays through Saturdays.
